He seems angry. Blaming superhero movies for where we are is giving far too much importance to superhero movies. The top ten grossing movies of the 80s were Top Gun (superior fighter jet pilot), Indiana Jones and the last Crusade (fantastic / superheroesque archeologist) , Back to the Future (Time travelling hero who evoked pop culture and whose father ended up writing about a time travelling superhero), Beverly Hills Cop (Superhero style cop Axel Foley), Ghostbusters (Superhero ghost hunters), Raiders of the Lost Ark (Indiana Jones, super archeologist again), Batman (speaks for itself), Empire Strikes Back (literally a continuation of the Hero’s journey), Return of the Jedi (and its sequel), and finally, ET, a literal Alien movie.
Every one of these movies suspends disbelief radically and presents escapist realities. Sometimes to fake Nazi Punching scenarios, sometimes back in time to a time, and some times far, far away. Every one of these movies were escapist. None of them were comedies or slice of lifes. They were all fantastic tales involving superheroic actions by the main character.
